of the reenforcing material, to selected parts of the fabric sheet, the portions of the sheet immediately contiguous to the folds thereof being unreenforced.

With the above and other objects in view,

the invention consists in the improved 20' method, as will be hereinafter more fully described'in detail, illustrated in the accompanying drawings, and subsequently incorporated-in the'subjoined clalms.

In the drawings, wherein I'have illustrated several applications of'my new method and the production of different articles, and in which similar reference characters designate corresponding parts throughout the several views,

Figs; 10 and 11 are plan viewsillustrating] an application of my new method in the production-of a billfold. v

Referring; in detail to the drawings, the. bill-and card case illustrated in Figs. .1 to 9 thereof, includes opposite side wall-s 5 of" equal area and of suitable length and width which are preferably formed from .a' single sheet of leather indicated at 6 folded, upon' itself as at .7, said leather sheethaving a suitable reenforcing material such as'silk secured to'theinner face thereof as shown With one of the side walls 5 ofthecase, an inner-pocket forming wall 9 is'associated and extends the entire length of the outer side wall 5. As indicated in Fig. 5 of the drawings this wall 9 which is also of silk or othersuitable flexible material has a re enforcing sheet za'dhesively secured on one side thereof, the edge of saidreenforcing; sheet indicated at 10 being: turned over and secured upon the opposite side face of the fabric wall. I p

A second bill receiving pocket is also provided in'conjunction with the" other outer side wall 5 of the case, while additional card receiving pocketsare provided on the wall 9; These; additional pockets are produced from a single sheet'ofsilk or other flexible material shown at 11. To one side of this sheet of fabric material and covering the entire area thereof, reenforcing sheet 12' of' fabric, paper or other material is adhesively secured; Opposite side edges of the material 11' are adapted to be turned inwardly upon and se cured to thereenforcing sheet 12, and inter;

mediate of said edges, the fabric sheet'll "is" adapted to be folded to provide a hinge fold" therein at 13 corresponding to the fold 7 connecting the opposite outer side walls 5 of the case. Therefore, after the sheet of reenforcing material 12 has been applied, narrow strips of this material indicated at 14 in Fig. 2 of the drawings, at the opposite edges 11 thereof, and at the fold 18 are removed. The reenforcing sheet 12 is relatively light, and these strips may be readily torn out and separated from the fabric sheet. 11. The edges of the sheet 11 are then turned inwardly and adhesively secured on the reenforcing sheet 12 as shown at 15 in Fig. 3.

Having thus prepared the several parts, the wall 9 is arranged in opposed relation to the relatively narrow reenforced section of the wall 11 at one side of the hinge fold 13 and is secured thereto by the spaced lines of stitching shown at 16, it being noted from reference to Fig. 6 that the wall 9 is of greater width than the part of the reenforced fabric sheet 11 to which it is secured. The connected parts 9 and 11 are then inverted from the position shown in Fig. 6 and arranged -in superposed relation upon the reenforced side of the outer flexible leather sheet 6 which forms the opposite side walls 5 of the case. The opposite longitudinal edges of the leather sheet 6 are then turned inwardly and then secured upon the reenforcing sheet 8 and the end edges of said leather 17. The opposite end edges of these parts sheet forming each of the outer side walls of the case is also turned inwardly and secured together with the end edges of'the parts 9 and 11 by the stitching indicated at and the corresponding end edges of the outer side walls 5 of the case are permanently secured together by the line of stitching 18. Thus, it will be understood that the latter end of the case is permanently closed.. From reference to Fig. 1, it will therefore, be seen that the folded reenforced fabric sheet 11 provides a bill receivingpocket extending the full length of one side wall of the case ly applied to the walls of the sheet llwhile. that part of the fabric sheet which forms the hinge fold 13, is unreenforced, so that it will occupy but relatively little space withln the bodyof the case at the fold line 7 thereof,

As the. opposite side walls of the case at one of their ends are unconnected, bills,-papers, or

memoranda may be conveniently and safely carried in the space between the walls of the card receiving pockets and the inner wall 9 of the bill pocket on the opposite side wall 0 the case; r

has the reenforcing sheet indicated at 21 adhesively secured to one side thereof, and in the illustrated instance, this sheet is of paper. At the points adjacent the fold lines 20, said paper sheet is perforated along the parallel lines 22 andone edge of said sheet between these lines ofperforationsis provided with the projections 23. Thus, after the reenforc-' ing sheet has been applied, these projecting.

edge portions 23 may be readily grasped, and the parts of the reenforcing sheet between the lines of perforations 22 readily torn out. These reenforcing sheets can be readily stamped out and provided with various other means, indicative of the particular portions thereof which are to be removed after the reenforcing sheet and the fabric sheet have been adhesively secured together.' As shown in Fig. 11, the unreenforced part of the fabric wall of the billfold extending along the fold lines 20 ma thus readily flex without undue buckling. have shown this inner wall of the billfold provided with card receiving pockets as indicated at 24, and to the unreenforced portions of the inner fabric wall of the billfold, the leather sections 25 are adapted to becentrally secured by the line'of stitching indicated at 26. The oppositely projecting portions of these leather sections have free sliding movement within the open ends of the pockets 24. However, no claim is made in this application to this particular typeor construction of billfold, as it is fully covered by patents heretofore granted to me.-

From the foregoing description considered in connection with the accompanying drawings, it will be readily apparent that by reason of my new method of applying the reenforcing material to the fabric sheet from which the walls of one of the bill pockets and the card receiving pockets are formed, loss of time incident to the making of proper measurements for applying the reenforcing material in sections to said walls so that there will be but a single thickness of material at the hinge line or fold which flexibly connects said walls, such operation is greatly ex-- pedited. Therefore,.billfolds, card cases and analogous articles of thiskind may be very rapidly produced in large quantities and at comparatively low manufacturing cost. I

have herein described and illustrated several desirable Ways in which my present method may be practiced, but it will be understood that the essential features of the 1nvent1on may be also carried out with the use of other structural forms of the materials than those herein referred to. Accordingly, I reserve the privilege of resorting to all such legitimate changes of this nature as may be fairly embodied within the spirit and scope of the invention as claimed. p

I claim:

1; The method of reenforcing' a flexible sheet of material to provide sections thereof flexibly connected by an unreenforced portion of the material whereby said sections may be relatively moved and folded into contact with each other, which consists in applying a sheet of reenforcing material to one side of the sheet of flexible material and securing said sheets together throughout their contacting faces, and thereafter removing a part of the reenforcing sheet to permit of the relatively free flexing of such unreenforced portion of the flexible material extending between and connecting the reenforced parts of said material.

2. The method of reenforcing a flexible sheet of material to provide sections thereof flexibly connected by an unreenforced portion of the material whereby said sections may be relatively moved and folded into contact with each other, which consists in adhesively securing a sheet of flexible reenforcing material to one side of the flexible sheet of material over the entire area of the latter, and then removing relatively narrow strips of the reenforcing material extending along parallel lines at opposite side edges of the flexible sheet of material and at an intermediate point thereof to thereby provide unreenforced edge portions of the sheet of material adapted to be turned over on the adjacent edges of the remaining portions of the reenforcing sheets and to also rovide an unreenforced portion of the flexit? material between said reenforced portions thereof capable of a relatively free folding or flexing action in the movement of the reenforced sections of said flexible sheet of material relative to each other.

3. The method of reenforcing a flexible sheet of material to provide sections thereof connected by anrunreenforced portion of the material whereby said sections may berrelatively moved and folded into contact with le sheet of i between and connecting the-reenforced parts.

each other which consists in perforating a 1 sheet of reenforcing material along spaced parallel lines and securing said sheets together in superimposed relation throughout their contacting faces, and thereafter tearing out and removing the part of the reenforc'ing sheet between said spaced lines of perforations to permit of the relatively free flexing of such unreenforced portion of the. first named sheet of flexible material extending
